The Cincinnati Bengals have officially announced signing C Ben Wilkerson to the active roster from the team's practice squad. Wilkerson was signed to a four-year contract. Financial terms of the deal were not disclosed.

Cincinnati Bengals C Ben Wilkerson (knee) was allowed to return to practice Tuesday, Nov. 8. He has been on the team's PUP list all season and now the Bengals have a three-week window where they can activate him, place him on season-ending Injured Reserve or release him.

As a correction to an earlier story, Cincinnati Bengals rookie OC Ben Wilkerson was not waived by the team. Rather he has been placed on the active/non-football injury list. Wilkerson remains with the team at training camp, but has not yet been cleared for practice as he continues rehab from a major knee injury he suffered last season in college.

Mark Curnutte, of the Cincinnati Enquirer, reports Cincinnati Bengals C Ben Wilkerson (knee) was not medically cleared to participate in the team's June minicamp, but is no longer listed by the team as injured. However, head coach Marvin Lewis noted not all of the players are cleared medically and they will need to have an official physical to confirm where they are health-wise.

Geoff Hobson, of Bengals.com, reports Cincinnati Bengals rookie C Ben Wilkerson (knee) has been doing work on the sidelines while the team practices at this weekend's minicamp. He is eight months removed from surgery for a torn patella tendon in his kneecap which is normally a six-to-nine month process. He had an encouraging visit to doctors earlier this week set him loose and he's confident he'll be ready for camp.
